Abstract EN
This paper presents a procedure for the response prediction and reduction in high-rise buildings under multidirectional wind loads.
The procedure is applied to a very slender tall building that is instructive.
The structure is exposed to both cross-wind and along-wind loads obtained from pressure measurements on a rigid model (scaled 1 : 100) that was tested in a wind tunnel with two different configurations of the surroundings.
In the theoretical formulation, dynamic equations of the structure are introduced by finite element and 3D lumped mass modeling.
The lateral responses of the building in the two directions are controlled at the same time using tuned mass dampers (TMDs) and active tuned mass dampers (ATMDs) commanded by LQR and fuzzy logic controllers, while the effects of the uncontrolled torsional response of the structure are simultaneously considered.
Besides their simplicity, fuzzy logic controllers showed similar trend as LQR controllers under multidirectional wind loads.
Nevertheless, the procedure presented in this study can help decision makers, involved in the design process, to choose among innovative solutions like structural control, different damping techniques, modifying geometry, or even changing materials.
